4. Applications (Focus on Construction & Multifield Use)
Tartaric Acid is a versatile organic acid with wide applications in food, pharmaceutical, construction and other industries, especially as an important auxiliary material in the construction field, specifically including:
-
Construction Industry (Key Application):
-
Concrete Additive: As a retarder and plasticizer, it can slow down the setting speed of concrete, extend the working time, improve the fluidity and workability of concrete, and enhance the strength and durability of concrete structures.
-
Building Cleaning Agent: Used to remove rust, scale and stains on building surfaces (such as copper components, stone materials and concrete surfaces), with mild decontamination effect and no damage to the base material, especially suitable for cultural relics and historical building maintenance to remove copper rust on bronze components.
-
Building Adhesive & Coating Auxiliary: Adjust the pH value of adhesives and coatings, improve the adhesion and stability of products, prevent the aging and discoloration of coatings, and extend the service life of building coatings.
-
Food Industry: Sour agent, flavor enhancer and preservative for beverages, candy, bakery products, canned food and jam; used in wine brewing industry to adjust acidity and improve wine quality, widely used in major domestic wine enterprises.
-
Pharmaceutical Industry: Excipient, acidulant and chiral reagent; used in the synthesis of drugs such as antibiotics and vitamins; used as a raw material for tartrate drugs (e.g., potassium sodium tartrate).
-
Other Applications: Organic synthesis reagent (chiral synthesis, oxidation-reduction reactions); electroplating industry (complexing agent); cosmetic industry (pH adjuster and skin care additive); food fermentation auxiliary (used in fermentation powder as an acidic component to promote gas production).
5. Packaging & Storage
5.1 Packaging
-
Food/Pharmaceutical Grade: 25 kg food-grade PP/PE bag (inner) + kraft paper drum (outer); 1 kg aluminum foil bag (small batch).
-
Industrial Grade (Construction Use): 25 kg PP bag (inner) + fiber drum (outer); 1000 kg jumbo bag; custom packaging available.
5.2 Storage
Store in a cool, dry, well-ventilated warehouse; keep sealed tightly to prevent moisture absorption and caking; avoid direct sunlight and high temperature; separate from alkaline substances, oxidants and food/beverages; avoid mixed storage and transportation.
5.3 Shelf Life
24 months for food/pharmaceutical grade; 18 months for industrial grade (construction use), under proper storage conditions.
5.4 Transport
Non-hazardous goods; transport in clean, dry vehicles; avoid collision, rain and moisture during transport; follow international, national and local transport regulations.
6. Safety & Handling
-
Personal Protection: Wear general protective gloves and goggles when handling; avoid direct contact with skin and eyes; if contact occurs, rinse immediately with plenty of water.
-
Handling Precautions: Avoid inhalation of dust; operate in a well-ventilated environment; do not mix with alkaline substances to prevent neutralization reaction.
-
Spill Handling: Clean up spilled powder with a dry broom, collect into sealed containers for proper disposal; rinse the contaminated area with water if necessary.
-
First Aid: In case of eye contact, flush with water for 15+ minutes; in case of skin contact, rinse with water; if ingested accidentally, drink plenty of water and seek medical attention if necessary.
